To find the area of the trapezoidal field, we can use the formula A = h(b1 + b2) / 2.
Plugging in the given values, we have A = 17(23 + 55) / 2.
Calculating the expression inside the parentheses, 23 + 55 equals 78.
Substituting this back into the original equation, we have A = 17(78) / 2.
Multiplying 17 by 78 gives us 1,326.
Dividing 1,326 by 2 results in an area of 663 square feet.
Therefore, there are 663 square feet of grass on the trapezoidal field.
Use the formula for the area of a trapezoid A=h(b1+b2)2
where A is area, b1
and b2
are the length of the bases, and h is the height, to answer the question. How many square feet of grass are there on a trapezoidal field with a height of 17 ft and bases 23 ft and 55 ft?
